解决方案

看不到的原因，第三的TextView 是你的布局有一个水平方向的同时前两个的TextView 取值适合屏幕大小，第三个是越来越外推。

要解决这个问题，你可以做以下几个步骤：

1 更改布局方向垂直的XML或Java文件，这样在的TextView 将出现一前一后垂直。

2 如果你想保持一个以上的的TextView 成一排，那么你还是应该设置您的主要布局方向为垂直，但的TextView 的每一行的使用code创建水平方向的新布局，并添加了的TextView 到此布局。

 的LinearLayout tvRow =新的LinearLayout（）;
tvRow.addView（firstTextView）;
tvRow.addView（secondTextView）;
 

最后这个布局添加到您的主要布局：

  mailLayout.addView（tvRow）;
 

I m giving 3 sentences in 3 text views in JAVA file in horizontal orientation but only 2 text view that is only 2 sentences are comin but the third sentence gets disappeared due to the resolution of the mobile. My query is how to get the third text view in a new line from the starting postion of the second line and not at the last.

public class MainActivity extends Activity {

private LinearLayout layout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    findViewById();
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    layoutParams.setMargins(10, 15, 10, 10);

    TextView tvTextsecond = new TextView(this);
    tvTextsecond.setText("Heywhatrudoingtoday");
    tvTextsecond.setLayoutParams(layoutParams);
    tvTextsecond.setBackgroundColor(Color.RED);
    tvTextsecond.setTextColor(Color.WHITE);
    //tvTextsecond.setSingleLine(true);
    layout.addView(tvTextsecond);

    TextView tvTextthird = new TextView(this);
    tvTextthird.setText("Haiitssundaytowork");
    tvTextthird.setLayoutParams(layoutParams);
    tvTextthird.setBackgroundColor(Color.BLUE);
    tvTextthird.setTextColor(Color.WHITE);
    //tvTextthird.setSingleLine(true);
    layout.addView(tvTextthird);

    TextView tvTextfourth = new TextView(this);
    tvTextfourth.setText("Owebullshitruuselessfellow");
    tvTextfourth.setLayoutParams(layoutParams);
    tvTextfourth.setBackgroundColor(Color.YELLOW);
    tvTextfourth.setTextColor(Color.WHITE);
    //tvTextfourth.setSingleLine(true);
    layout.addView(tvTextfourth);

}

private void findViewById() {
    layout = (LinearLayout) findViewById(R.id.flowLayout);

}

}

解决方案

The reason you don't see the third TextView is that your layout has a horizontal orientation and while the first two TextViews fit the screen size the third one is getting pushed outside.

To fix this issue you can do several steps:

1. change your layout orientation to vertical in the XML or the java file, and that way the TextView will appear one after the other vertically.

2. if you want to keep more then one TextView in a row, then you should still set you main layout orientation to vertical, but for each row of TextView's create a new layout with horizontal orientation using code and added the TextView to this layout.

LinearLayout tvRow = new LinearLayout();
tvRow.addView(firstTextView);
tvRow.addView(secondTextView);

Finally add this layout to your main layout:

mailLayout.addView(tvRow);
